put Your commands into /etc/rc.d/rc.local script (is started with system startup)

su - user1 -c "screen -dm python -p 8765 ..."

Hi,

You may add a startup script under /etc/rc3.d

The script name should look like SnnName

e.g. S99startmyserver

the script should be executable

chmod +x /etc/rc3.d/S99startmyserver

The script should all necessary setting of env variables and full path names to commands and files

root@<server path>/bin # su - user1 -c "screen -dm python tinyerp-server.py "

now "screen -r" return "There is no screen to be resumed." What I am doing wrong?

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

tinyerp-server.py should not go backgroud. Does it? If it goes, then You don't need the screen to control it?
Or maybe try full paths like
/usr/bin/python /path/to/tinyerp-server.py

I need to start more than one server. I need to use "screen -r". And I cannot start server like /path/to/tinyerp-server.py as it cause some problem with application root reference. Can you help me with this.

Why those servers have to be run from within screen?
Screen is needed if the server will not detach from controlling terminal.

another option is to use nohup(man nohup)

> I need to start more than one server.
Run more screens.

> And I cannot start server like /path/to/tinyerp-server.py
make sure CWD is /path/to/
